O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 Who hath made the earth for you a carpet and the heaven a structure, and sent down from heaven water, and brought forth therewith fruits as a Provision for you; wherefore set not up compeers unto Allah while ye know. 22 And if you be in doubt whether the Book We have sent down to Our Servant is from Us or not, then produce, at least, one Surah like this. You may call all your associates to assist you and avail yourselves of the help of any one other than Allah. If you are genuine in your doubt, do this. 23 And if you cannot do it - and most certainly you cannot do it - then be conscious of the fire whose fuel is human beings and stones which awaits all who deny the truth! 24 And convey good news to those who believe and do good deeds, that they shall have gardens in which rivers flow; whenever they shall be given a portion of the fruit thereof, they shall say: This is what was given to us before; and they shall be given the like of it, and they shall have pure mates in them, and in them, they shall abide. 25 ۞ Well, Allah is not ashamed to cite the similitude of a gnat or of something even more insignificant than this. As for those who believe, they come to know from the same similitude that it is the Revelation from their Lord; but those who disbelieve, say, "What does Allah mean by such similitudes?" Allah leads astray many and guides many to the right way by the same thing. And He leads astray only those who disobey Allah; 26 Who, having sealed it, break God's covenant, dividing what He ordained cohered; and those who spread discord in the land will suffer assuredly. 27 How do you disbelieve in God, seeing you were dead and He gave you life, then He shall make you dead, then He shall give you life, then unto Him you shall be returned? 28 It is He who created for you all that is in the earth, then He lifted Himself to heaven and levelled them seven heavens; and He has knowledge of everything. 29
